Article contents:== Outdated egg! This is an egg for CHICKEN 3, the unsupported old release. You're almost certainly looking for [[/eggref/4/nest-tool|the CHICKEN 4 version of this egg]], if it exists. If it does not exist, there may be equivalent functionality provided by another egg; have a look at the [[https://wiki.call-cc.org/chicken-projects/egg-index-4.html|egg index]]. Otherwise, please consider porting this egg to the current version of CHICKEN. [[tags: egg]] == nest-tool === Introduction The nest-tool egg provides both an extension and a command-line tool to parse and extract information from eggs repository listings. === Author Mario Domenech Goulart === License BSD === Requirements [[http]], [[tool]] === Parameters and procedures '''parameter:''' nest-tool:repository Path or URL (HTTP) for the repository data file. Default is {{http://www.call-with-current-continuation.org/eggs/repository}}. '''procedure:''' (nest-tool:raw) Returns the data read from {{(nest-tool:repository)}} '''procedure:''' (nest-tool:egg-name egg) Returns the egg name from EGG (an item (a list) from {{(nest-tool:repository)}}). '''procedure:''' (nest-tool:egg-date egg) Returns the release date from EGG (an item (a list) from {{(nest-tool:repository)}}). '''procedure:''' (nest-tool:egg-file egg) Returns the egg filename from EGG (an item (a list) from {{(nest-tool:repository)}}). '''procedure:''' (nest-tool:egg-dependencies egg) Returns the list of dependencies from EGG (an item (a list) from {{(nest-tool:repository)}}). '''procedure:''' (nest-tool:names #!optional raw) Returns a list of eggs names from {{(nest-tool:raw)}}. If RAW (a list) is provided, it is used instead of {{(nest-tool:raw)}}. '''procedure:''' (nest-tool:dates #!optional raw) Returns an alist {{'((eggname . release-date) ...)}} from {{(nest-tool:raw)}}. If RAW (a list) is provided, it is used instead of {{(nest-tool:raw)}}. '''procedure:''' (nest-tool:files #!optional raw) Returns an alist {{'((eggname . filename) ...)}} from {{(nest-tool:raw)}}. If RAW (a list) is provided, it is used instead of {{(nest-tool:raw)}}. '''procedure:''' (nest-tool:dependencies #!optional raw) Returns a list '{{'((eggname dep1 dep2 ... depn) ...)}} from {{(nest-tool:raw)}}. If RAW (a list) is provided, it is used instead of {{(nest-tool:raw)}}. '''procedure:''' (nest-tool:search-names pattern #!optional raw) Searches for PATTERN (a regex object or a string representing a regex) in eggs names from {{(nest-tool:raw)}}. If RAW (a list) is provided, it is used instead of {{(nest-tool:raw)}}. '''procedure:''' (nest-tool:search-dependencies pattern #!optional raw) Searches for PATTERN (a regex object or a string representing a regex) in eggs dependencies lists from {{(nest-tool:raw)}}. If RAW (a list) is provided, it is used instead of {{(nest-tool:raw)}}. ==== Examples csi> (nest-tool:search-names "meta.*") ((metakit ((date "200610211943")) "metakit.egg") (meta-setup ((date "200706181512")) "meta-setup.egg" tool format-modular http topological-sort) (metaphone ((date "200705190012")) "metaphone.egg" miscmacros misc-extn)) csi> (nest-tool:dependencies (nest-tool:search-names "meta.*")) ((metakit) (meta-setup tool format-modular http topological-sort) (metaphone miscmacros misc-extn)) The eggs which depend on [[spiffy]] csi> (nest-tool:names (nest-tool:search-dependencies "spiffy")) (ajax phoghorn web-scheme spiffy-utils) The number of eggs in the repository: csi> (length (nest-tool:raw)) 303 === The command line tool $ chicken-nest-tool -h usage: chicken-nest-tool [OPTION | ARGUMENT] ...
